LAMP-HEATER.

LZELMM.

Specification of Letters Patent.

Patented June 26, 1917.

Application filed April 25, 1916. Serial No. 93,528.

To all whom it may concern:

Be it known that I, EDWIN JOSEPH MARK- HAM, a subject of the King of Great Britain, residing at l/Vatrous, in the Province of Saskatchewan and Dominion of Canada, have invented certain new and useful Improvements in a Lamp-Heater, of which the following is a specification.

My invention relates to a heater adapted to be used inconneetion with a lamp, whereby a room, tent, or the like may be quickly and inexpensively heated by utilizing the heat of the lamp.

Another object is the provision of a heater comprising a metal drum having a circular base provided with a central aperture, the said drum having an inner drum concentrically mounted therein in spaced relation to the outer drum, said inner drum adapted to hold and radiate heat which is directly transmitted thereto by the flame of the burner through the central aperture of the base.

A further object is the provision of a.

may be secured to the supporting stand, the.

said stand being further adapted to support cooking utensils, or the like, when the heater is not in use.

With these and other objects in view the invention consists in the construction and combination of the various parts as will be hereinafter more fully described and pointed out in the appended claims.

In the drawings:

Figure 1 is a vertical cross section through the heater, and a supporting stand, the lamp being shown in elevation.

Fig. 2 is a top plan View of the heater.

Fig. 8 is a detail view of the fastening device whereby the heater is secured to the supporting stand.

The numeral 1 indicates a lamp provided with a burner 2. A support or stand comprising a circular platform 3 having a central opening and an annular depending flange 4 projecting from the edges of said opening, the said flange being adapted to fit around the burner 2 of the lamp and rest upon the shoulder 2 provided for supporting the platform in position. The flange 4 hasdraft openings 4 therein at its upper end. The platform 3 is further provided with an upwardly extending flange 5 and, is

adapted to receive the hollow integral base 6 of a heater 7. As will be noted, the circular base (3 of the heater is provided with brackets 8 in which are pivotally nlounled hooks 9 adapted to be swung downwardly to engage the bottom of the platform 3, whereby the heater is securely attached to the stand.

The heater 7 comprises an outer metal drum 10 which has integrally formed therewith the above described circular base 6 and having a central aperture 11 registering with the central opening in the platform A smaller metal drum 12 is concentrically mounted within the drum 10, and extends the full length thereof, and is supported in spaced relation to the outer drum 10 by means of stay bolts 13.

In use, the heater is placed in position, as illustrated in Fig. 1, upon the stand 3 and is secured by means of the fastening devices 8. It is apparent that the heat of the lamp will then be directed against the inner drum 12 and the said drum will hold the heat until it is heated to a very high temperature whereupon the heat will radiate from said inner drum, thus heating the outer drum from which it is radiated to heat the surrounding atmosphere. As will be seen the products of combustion are adapted to escape by passing upwardly through the space between the inner and outer drums and through the apertures 15 provided in said outer drum.

l Vhen it is not desired to use the heater, it will be noted, that by removing the same from the stand 3, a cooking utensil, or the like, may be substituted therefor and the l fiea'i of the lamp utilized in the cooking of It will also be understood that articles such as gloves, shoes, or the like may be placed within the interior of the drum 12 for purposes of heating and drying the same and for keeping foodstuffs warm.

I claim:

1. A lamp heater comprising a hollow support removably supported by the lamp and disposed over the burner thereof, a platform provided at the upper end of the support, a heater body having a base flange thereon adapted to be removably disposed on the platform and having communication with. the hollow portion of the support whereby heat is conveyed from the lamp to the heater body.

2. A lamp heater comprising a hollow support removably supported by the lamp and disposed over the burner thereof, a platform carried by the upper end of the support, a heater body having a base flange projecting therefrom and adaptedto. rest; on.

the platform, said heater body having communication with the hollow support whereby heat is conveyed from the burner to the heater body, and means for removably securing the base flange to the platform.

Av lamp heater comprising an outer metallic drum, aninner metallic drum of lesser diameter concentrically mounted within said outer drum, saidouter drum provided with a plurality of apertures for the escape of the products of combustion, a circular base formed integrally withsaid outer drum having a central aperture communicating with the interior of said outer drum, a circular platform adapted to. receive said circular base of the outer drum, hooks pivotally connected adjacent thev periphery of said circular baseadapted to be swung downwardly into engagement with the circular platform to releasably secure the heater to said platform, and a depending annular flange formed integrally with said platform to engage the burner of the lamp, said platform adapted to receive a cooking utensil when the heater is removed therefrom.

a. A device of thecharacter described comprising, in combination, a lamp having an annular shoulder adjacent the burner thereof, a support having a platform having a central'opening therein and a depending annular flangeprojecting from the edges'of said opening, said flange being adapted to fit around the burner of-the lamp to rest upon said'shoulder, an upstanding annular flange provided on the outer. edge ofsaid platform, a drum having a circular; base portion formed on one side, thereof and adapted .to rest upon .said platform to fit the innerhfacei of said upstandingflange, said base portion having acentral opening therein communicating with thevinterior of the drum andadapted to register with the central opening in said platform, hollow inner drum of less diameter than said first drum and disposed within the latter, and means for holding said inner drumin spaced relation relative to the walls of-said first drum.

In testimony whereof I affix my signature in presence of two witnesses.
